4.6.7 IP Filtering Settings
Operation Mode -> Setup -> IP Filtering Settings
IP filtering is simply a mechanism that decides which types of IP datagram will be
processed normally and which will be discarded.
This allows you to define rules for allowing / denying access from / to the Internet. Please
do set both inbound/outbound in order to get complete connection. Only inbound or
outbound will not allow to get response from the destination IP.
Disable IP filtering: No IP filtering is performed.
Grant IP access: Data traffic satisfying rules below are allowed / forwarded.
Deny IP access: Data traffic satisfying rules below are denied / filtered.
